UNITED STATES PATENT Fl lClEG JOHN JAMES KNIGHT, OF TORONTO, ONTARIO,CANADA.

DRAW-HEAD FOR RAILWAY-CARS.

SPECIFICATION forming part of Letters Patent No. 388,882, datedSeptember 4, 1888.

Application filed Juno 2. 1888. Serial No.27z1892. (No model.)

To all whom it may concern.-

Be it known that I, J GEN JAMES KNIGHT, carpenter, of the city ofToronto, in the county of York, in the Province of Ontario, Canada,haveinvented new and useful Improvements in Draw-Heads for Railway-Cars;and I do hereby declare that the following is a fulhclear, and exactdescription of the same.

My invention relates to draw-heads now in use with the common link andpin; and it consists in a sliding trip operated backward by the linkwhen being pushed into the draw-head, and forward by a spiralcomprcssion-spring. The trip consists of around bar with flattened endhaving a hinged head-piece thereon,which is pressed up on the under sideof the roof of thedraw-head byacoinmon flat spring doubled in themiddle, and is kept down by a small pin in the said roof behind thedraw-pin,allowing the spiral compressed spring to force the trip forwardto hold the link or pin,as the case may be. The said spiral spring actsdirectly on the headpiece in front and on a stationary block behind, andis supported by the round bar forminga part of the trip hereinbeforereferred to.

Reference being had to the accompanyin drawings, Figure 1 is a side viewof my drawhead with one of the sides removed to show the working partsthereof. Fig. 2 is a plan View with the upper part or root removed forthe same purpose. Fig. 3 is a detached side view of the head-piece,showing in dotted lines the flat spring hereinbefore referred to.

Similar letters of reference indicate similar or corresponding parts.

A represents the drawhead; a, the upper part or roof of the same; I),the under part or floor of the same; 0, the left side thereof; d, theright side; e, the hinged head-piece of the trip; e, the pivot pinthereof; 6*, asloping notch;f, the fiat end of the bar g, with flatspring h in dotted lines,hereinbefore referred to; z, the spiralcompressioirspring, which forces forward the trip by acting on theheadpiece e in front and the block j behind. it represents the pin and lthe link; m, the small pin in the roof for keeping down the head-piecee. A cross-pin, n, is also shown in a notch in the aforesaid pin on.

The operation of the trip when coupling is as follows: The coupling-linkis of such length that in coupling the cars the draw-heads will coineincontact before each head piecewill have traveled two inches, or nearlyso, so that the force of the percussion from the ears coming togetherwill be received by the percussionspring on the inner ends of thedraw-heads and will be spent therein, and protecting the trip from beingdamaged thereby.

Having th s described my invention, 1 claim 1. A sliding trip for thedraw-head of railway-cars,constructed with a head-piece hinged on thefront and flat end of a round bar provided with a flat spring forpressing up the headpiece on the under part of the roof of thedraw-head, and a spiral compression spring with fnlerunrblock behind forpressing forward the trip, said head-piece keptdown by a small pin inthe roof of the draw-head.

2. In a d raw-head constructed with the com mon link and pin andpercussion-spring at. the back end thereof, the combination of a slidingtrip with head-piece e, pivot-pin a, and small pin m on roof of thedraw-head with notch and cross-pin n, a bar, fg,with fiat spring 71,spiral compression-spring i,with fulcrum-block j,arranged and operatingas set forth.

3. The under part of the roof of the drawhead constructed with a notch,e", sloping upwardly toward the mouth thereof to receive and hold inposition the hinged headpiece e of the trip previous to the action ofthe link thereon.

JOHN JAMES KNIGHT.
